IBM DS3400 configuration
Posted on 2011-10-06
We are running an IBM D3400 kit – from about 4 years ago, we were running windows 2003 and had like 4 hosts and all was good, it is attached through a 205-16b fabric switch of which 8 ports are active. So theoretically we have 2 ports left.
As I recall we didn’t have issues attaching the host machines at that time – we put Emulex 4GB lightpulse cards in the hosts and they were discovered and we assigned host to logical drive mappings.
Now we need to add 2 more servers of which 1 is 2008 and the second is 2008 R2, I have a 1 channel card in the 2008 server and a 2 channel card in the R2 machine (of which we will only use 1 channel for now). I used the latest HBAnywhere and it seems to like the drivers in each host.
We are using IBM Storage Manager II software but I had to manually add the hosts. And although I can see them (as I recalled previously once this was all accomplished the drives showed up on the respective hosts), but now (in disk management (windows), I see unallocated drives that are the size of the SAN volume in question, but don’t seem to be able to access them.
I do notice that in (see attached pictures) that there isn’t an access (lun 31) for either of these servers.
Could this be my issue? Can you tell me how to correct this.
